GRAIN-SCOURER.

SPECIFICATION forming part of Letters Patent No. 559,488, dated IVa-y 5, 1.8961.4

Application led February 5, 1894:.

.To @ZZ whom t may concern.-

Be it known that we, VILLIAM YV. HUNT- LEY, residing at Silver Creek, in the county of Chautauqua, and FREDERICK DWOLFROM,

residing at Rochester, in the county of Monroe, State of New York, citizens of the United States, have invented new and useful Improvements in Grain-Scourcrs, of which the :following is a specification.

rlhis invention relates to that class of scou rers which consist, essentially, of a drum prowided with scouring-teeth and revolving withiin a chamber having scouring-teeth.

The object of our invention is to produce a i5 scourer of this character which has a gentle scouring action and which is particularly suitable for scouring malt, seeds, and beans preparatory to cleaning the same by a separator employing an air-current.

In the accompanying drawings, Figure lis a longitudinal sectional elevation of a separator provided with our improved scourer. Fig. 2 is a fragmentary sectional elevation of the scourer, on an enlarged scale. Fig. 3 is a horizontal section in line 3 3, Fig. 2. Fig. 4

is a fragmentary section of one of the scouring-teeth and its supporting-plate, on an enlarged scale. A

Like letters of reference refer to like parts 3,0` `in the several figures.

Although our improved scourer can be operated independently of any other machine, we have shown it in connection with a separator in which air-currents are employed, and

3 5v which consists, essentially, of a main frame A, shaking-shoe B, containing the sieves b, feed-box C, preliminary wind-trunk D and cheat-hopper D', iinal wind-trunk E and (chess-hopper E', and a fan F.

40 ,Gr.eprcsents a scouring-chamber formed in serai ivo/499,118. (No model.)

`tical rear plate, while the front plate 7i is pivoted with its upper end to the vertical front plate H. The lower end of the pivoted plate 7L is separatedfrom the lower end of the rigid plate h', formin gan ou tiet-opening hthrough which the material passes from the scouringchamberinto the feed-box. The pivoted plate 71, can be adjusted toward and from the rigid plate h', for regulating the flow of the material, by means of a screw t', arranged in the `front wall of the feed-box and bearin gagainst the front side of the pivoted plate.

J represents scouring-teeth which are regularly disposed on the inner sides of the plates H H 7L h and in planes parallel with the longitudinal direction of the plates. Each of these teeth consist of a piece of round wire bent into a U-shaped staple. These staples are firmly secured with their arms to the scouring-plates, preferably by placing the staples in a mold and casting the plates upon the ends of the staples.

K represents a scouring drum or cylinder arranged in the scouring-chamber lengthwise between the scouring-plates and mounted on a shaft 7c, journaled with its ends in bearings 7d, arranged in the end walls of the scouringchamber. y

M represents segmental scouring-plates secured to the outer side of the cylinder and provided with scouring-teeth m, arranged to pass between the teeth of the scouring-plates. These teeth have the form of staples which are arranged in planes parallel with the axis of the scouring-cylinder, to correspond to the position of the teeth on the scouring-plates II H 7L 7L. The teeth ofthe scouring-cylinder are secured to the segmental plates preferably by casting, in the same manner as the stationary scouring-teeth are secured to the scouring-plates.

Upon rotating the scouring-cylinder when the scouring-chamber is iilled with grain, seeds, or other material to be scoured the teeth of the cylinder pass through the grain and also carry the same against the stationary teeth, thereby scouring the grain and removing the particles of dust andimpurities therefrom. By constructing the scouring-teeth in the shape ofl staples, which are arranged in and scouring-plates, a larger scouring-surface n is secured, because the grain is rubbed in passing through on the inner sides of both legs of the staples and also around the outer sides thereof. This construction of a scour* ing-tooth also enables the same to readily pass through the material Without carrying the latter around With the cylinder to any extent, thereby enabling` the machine to be run with less power.

By making the staples of round Wire the scouring action of the same is very mild, which is particularly desirable for scouring malt and other grains or seeds requiring gentle treatment. The grain is thoroughly scoured in the feed-box and also agitated therein by the scouring mechanism, whereby the feed is equalized and clogging is prevented, The grain is then immediately subjected to the action of the airlcurrent in the preliminary Wind-trunk, land passes ,thence to the shakingfshoe, Where itis screened, so that these several operations are performed in close connection in the same machine.

NVe claim as our invention- The combination with a scouring-chamber and a toothed scouring-cylinder arranged therein, of toothed inclined plates forming the bottom of .said scouring-chamber, one of said plates being hinged and provided with an adjusting device whereby the opening between the tWo plates can be regulated, substantially as set forth.

Vitness our hands this 27th day of J anuary, 1894.
